Test portability lets automation code operate across contexts and integration tools with limited change. Layered architecture separates business-focused test behavior from lower-level integration details, allowing reusable code to support multiple suites and teams. section 15.0
Design portability around a stable programming model and an replaceable integration layer:
- Abstract the underlying test integration tool behind consistent APIs. section 15.2.1
- Keep test code unchanged when running component tests with Playwright or cross-browser tests with WebdriverIO. section 15.2.1
- Reduce integration-tool lock-in so a supported tool can be replaced without rewriting existing tests. section 15.2.1
One test codebase, different web tools
A team can use Playwright for component tests and WebdriverIO for cross-browser tests while retaining the same test code. The portable Integration layer absorbs the tool-specific differences. section 15.2.1
